The device is utilized to provide swirling of either intake air flow or exhaust gas flow of an internal combustion engine. When used to swirl intake fluid flow, the device is positioned in the intake passageway for air entering the carburetor or fuel injection subsystem. The swirling of the air provides more complete mixing of the air and fuel entering the combustion chamber of the engine thereby providing more complete combustion of the fuel mixture. When utilized to swirl exhaust fluid flow, the device is positioned in the exhaust passageway for exhaust gases exiting the exhaust manifold. The swirling of the exhaust gases minimizes slowing of exhaust gas flow through the exhaust system to reduce back pressure and thereby provide more complete combustion. The device includes a set of flat planar vanes which are mounted within a housing. The varies are angled to impart a swirling motion to the intake air or exhaust gas passing through the housing. The vanes are also provided with curved trailing edges to minimize impediment to fluid flow passing through the housing and provided with angled trailing end portions to enhance effectiveness of the vanes in imparting a swirling motion to the fluid flow.
